The OI Series High Power Optical Isolator is designed for high power applications by guiding light in the normal direction while block back reflection the reverse direction. With Photonwares’s proprietary in-fiber beam expansion technology that scale down the power density, these components can intrinsic handle optical power beyond 20W. With our proprietary magnetic-optics technology and proven advanced micro optics design, it features low insertion loss, high isolation, compact structure, and high stability. They are tested under high power before shipping. This product has leading industrial performance. The OI isolator can be made using a variety of fibers including HI980, HI1060, LMA and other double cladding fibers. Customized designs are available to meet special applications.
